Masaki Ando is a seventeen-year-old young man who originates from the surface world but is summoned to the subterranean realm of La Gias to become the pilot of the Cybuster, one of the four legendary Masō Kishin. He is a classic hot-blooded personality, excelling in athletics and physical tasks but often impulsive and lacking in careful thought. His parents died when he was very young, which left him with a deep-seated loneliness that was eventually eased by the people he met in La Gias. In the story of Super Robot Wars OG: Divine Wars, Masaki appears as a supporting character who has followed the mysterious and dangerous Shu Shirakawa to Earth, driven by a fierce personal vendetta. Shu murdered Masaki's beloved mentor and father figure, Zeoroot Zenozakis, and Masaki is determined to stop him and avenge that loss. Despite his serious goal, Masaki often provides comic relief due to his terrible sense of direction, his awkwardness around women, and the teasing of his two intelligent cat-like familiars, Kuro and Shiro, who assist him in battle by piloting remote weapons called High Familiars. He pilots the Cybuster, a wind-elemental mecha that requires a pilot with high prana, or life energy, which Masaki possesses thanks to his intense emotions. The Cybuster can transform into a high-speed bird form called the Cybird and wields powerful weapons including the mystical Dis-Cutter sword, the wide-range Cyflash attack, the charging Akashic Buster, and the all-consuming Cosmo Nova. Over the course of the Divine Wars conflict, Masaki evolves from a lone avenger into a reluctant but dependable ally of the Earth Federation Forces, particularly those aboard the battleship Hagane, as he learns to set aside his personal grudge when the greater threat demands it. Key relationships include his deep respect for the memory of Zeoroot, his protective fondness for Zeoroot’s daughter Presia, his complicated romantic feelings for the engineer Wendy Rasm Iknart (further complicated by the assertive Lune Zoldark), and his bitter rivalry with Shu Shirakawa, who is both his nemesis and a figure Masaki cannot help but begrudgingly respect as events unfold. Masaki’s motivations are rooted in personal vengeance but broaden to encompass the protection of both La Gias and the surface world from destruction, making him a steadfast if occasionally scatterbrained warrior.
